No dig at you envy T, but this is brought up from time to time that AFR's are a bit high, low etc. What range should they sit in? Link to comment Share on other sites More sharing options...

By the way, that's very good power for a generic tune! Link to comment Share on other sites More sharing options...

Posted 29/05/07 07:20 AM Share Posted 29/05/07 07:20 AM Everyone I speak to tells me that AFR's should be in the low 12's, accross the power curve. Silhouette's nudge 13, and this IMHO is to high. With the stock squirters and 12.2-12.5 afr, power would be about 10-15 rwkws less.This is just what I have been told. Link to comment Share on other sites More sharing options...

This just illustrates how sh*t the stock injectors actually are, they really can't flow enough fuel for these motors to run boost up top, we have seen it time and time again with all different tune houses. Even custom tunes see these lean AFR's. Now AFRs will also vary from application to application I.e how much boost you run, what type of fuel you use and if your car is Turbo, naturally aspirated ect. There is many factors that go into influencing what a desired AFR for a particular application should be, e.g leaner the mixture the higher the combustion chamber temps, the more prone a motor is to detonating and melting a piston. I hope the timing is kept on the conservative side on this tune Edited 29/05/07 07:26 AM by Fat-Tony Link to comment Share on other sites More sharing options...
